This 3 ingredient peanut butter mug cake is the perfect dish if you are in search of a quick and easy treat at home without making too much fuss in the kitchen; it is easy, delicious, gluten-free and low in carbs.
In a small mixing bowl, whisk together all the ingredients until combined.
Transfer the batter into a microwave-safe mug or ramekin. Scatter chocolate chips on top (if using).
Microwave for 45 seconds-1 minute. Remove from the microwave and allow it to sit for a minute before eating.
The mug that you use must be sturdy and heat-resistant (you don't want your cup to crack) but also not become excessively hot to hold the mug cake while it is being baked in the microwave.
To remove the mug from the microwave, place an oven glove or a tea towel around the handle. Allow the mug cake to cool for a few minutes before cutting into it.
Do not overcook! It takes no longer a minute to bake this dish, and overcooking it will result in a dry and hard mug cake opposite to the fudgy, rich, and moist one that we are trying to achieve.
An easier substitute for granulated sugar is brown sugar. It is widely available, and it makes for a darker, denser, and moist mug cake. It also coaxes out all the desirable flavors in the dish.
There are many options for toppings you may choose from other than chocolate chips. For soft and creamy toppings, you may top your mug cake with whip cream. If you want a pillowy texture, you may consider using marshmallows instead. However, if you prefer your homemade mug cake as it is, you don't have to add any toppings at all.
Substitute sugar with any sweetener, and this recipe will be keto-friendly too.
